Content-Oriented Network Project

Network assisted architecture enables efficient information dissemination


From server-centric communication to content-oriented networking

  Traditional IP based one-to-one communication potentially degrades data transmission quality, especially when a server is located far from clients or a network is congested. Although CDN and cloud computing escape from some of the troubles, yet it is difficult to optimize the transmission quality and the network resource usage. On the other hand, many users tend to access to the same contents even in the recent Internet. According to these aspects, we study the content-oriented networking, which makes network itself cache popular contents and assist users in retrieving contents.


We aim at developing technologies of optimizing transmission quality and improving network resource usage

  In the content-oriented networking, a user specifies a content name (or identifier) to retrieve data, not only from a publisher but also from in-network cache. This technology improves data transmission quality and provides effective network resource usage. It can be also applied for real-time communications. For example, it contributes to live streaming applications broadcasting contents to many users, or sensor applications collecting a huge amount of data from distributed sensors.


The content-oriented networking technology we apply will provide effective information sharing and dissemination and lead the great possibilities for the future Internet

●Distributing contents through optimized path(s) (instead of relying on shortest path)
●Developing distributed in-network cache algorithms

●Supporting real-time as well as delay tolerant communications

  We will evaluate our research outcomes in a large scale testbed or the Internet, and work toward practical use of the future Internet technologies. The evaluated technologies will contribute to the safe and security social infrastructure in the future.
